COMBINED PUMP AND IVIEASURIE.

SPECIFICATION forming part of Letters Patent N. 624,550, dated IVIy 9, 1899".

Application tiled April 22, 189.8. Serial No. 678,461. (No model.)

To 1f/ZZ whom, t may concern:

Beit known that I, HUGO SCHNEIDER, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in a Combined Pump and Measure; and I do declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to a combined pump n and measure; and the object of the invention is to provide means for pumping liquids and the like from vessels and at the same time measuring and recording the amount as it is pumped, substantially as -shown and described, and more particularly pointed out in the claims.

Figure 1 is a side elevation of my improved pump and measure within a barrel and as in use. Fig. 1, but broken into sections. side View of the outer end of the spout with the valve therein.

Fig. 2 is a sectional view enlarged from g Fig. 3 is a Fig. 4 is a perspective View of the three separate parts of the piston kept upon its seat 7 by a light spring 8, in- I passage for the discharge of the liquid. The

piston B is designed to work back and forth within the casing 2, and this pistonl is oonstructed in three parts, as more clearly shown in Fig. 4. The upper part 10 has a central boss 11, with an opening 12 therein, and this boss is supported on part 10 by radiating arms 13, thus giving a free and open space between part 10 and boss 11 for the passage of the liquid. The lower part 14 of the piston is threaded into part 10 and is made open at the bottom, with a seat 15 for the valve 16. The valve 16 has guide-lugs 17, and a central stem 18 projects upward into the opening 12. A spring 19 encircles this stem and bears against the bottom of the boss 11 and assists in keeping the valve 16 closed when in one of the operating positions.

j Now in order that the pump A may be supported I employ a tube 20, screwed into the top of the casing A, and an adjustable Banged collar 22 is free to slide over this tube, and a bolt 23 fastens this collar at any height, aocordingto the height of the barrel or vessel that the tube is within. As here shown, the flange of the collar 22 has screw-holes, and it is by this means that it is tacked or screwed on the head of the barrel, thus providinga rigid support for the Whole structure.

The body C of the spout 24 is screwed on and supported at the top ofthe tube 20, and a valve 25 is seated within the outer end of the spout 24. The stem 26 of this valve is supported by the nut and bushing 27, screwed into the top of the outer spout-chamber 2S. Screw 29 on stem 26 rides Within the inclined slot 30 in nut 27, and when the handle 31 is turned the valve is raised from its seat. The reverse motion will close the valve. This valve is located at the extreme outer and lower end of the spoutgand is designed to pre-Y vent the loss of liquids that remain in the end of the spout after each withdrawal. Cleanliness is thereby obtained, and Where liquids, such as molasses orthe like, are used flies and insects are kept out ot the end of the spout, and when the nekt withdrawal occurs there is no danger of any foreign or unclean matter being discharged withthe liquid.

In order to operate the pump-piston B, I provide' the body C with a recessed extension or housing 33, Within which a short rockerarm 34, mounted on the cross-shaft 35, is free to operate. The end of this arm 34 is pivoted to a piston-rod 36, which passes down through tube 2O to the piston B. The lower end of the piston-rod and the piston B is provided with a ball or swiveled joint 37 and nut 38, and this construction allows the slight lateral play ot the rod when the arm 34 is operated.

operate this arm, I attach a lever 39 to the end of the shaft outside of the body C, and a certain fixed and adjusted movement of this lever 39 serves to operate the piston B to pump a certain amount of liquid at each full stroke.

v an immediate flow.

To determine this amount and to adjust the stroke, a beveled arm 40 is adj ustably mounted on the top end of the lever, and the beveled edge of this arm comes in contact with a lug 4l on the body C, thus limiting the movement of the lever in this direction. The lower end of the lever comes into contact with a projection 42 when thrown in the opposite direction. The movement of this lever is also utilized to register the amount of liquid pumped, and t0 this end a dial 43 is rotatably mounted on the side of the body C, and a spring-pressed finger 44, pivotally supported on the extremity of the lever, engages the ratchet-teeth on the edge of the dial when the said finger is brought forward. A finger 45,

supported on lug 41, indicates the movement of the dial, and figures on the face thereof show the amount of liquid pumped.

From the dotted position of the lever shown in Fig. l it will be seen that the lever must practically travel its full distance before the finger 44 engages the dial and records the amount of liquid pumped, and this is so intended to prevent the giving of a short measure.

As seen in the drawings, the pump A is at the extreme bottom, where the en tire contents of the vessel can be emptied. When in use, the pump A, tube 20, and spout 24 are always filled to the valve 25 in the spout, and when the operator depresses the handle 39 l[here is The amount of this flow isdetermined by the length of the stroke of the pistonV B. When the piston rises, the valve l'closes and forces the liquid up and through valve 25, which has previously been opened. The lower valve 4 opens as the piston B rises, and the liquid is drawn into the chamber of pump'A. Vhen the piston descends, the pressure closes valve 4, and the liquid in the chamber forces valve 16 open, thus allowing it to pass and fill tube 20, and thereby keeping the tube and pump full at alltimes. Theamountofliquidtobepumped at each stroke can be exactly determined by setting the beveled arm 40, and a certain number of strokes will discharge a given quantity of liquid. Thus four strokes will discharge a pint, eight strokes a quart, and so on. This measurement is accurate and is accomplished by and is due to my construction. By plac- This stroke can be lengthened or shortened by the arm 40, as heretofore described.

By reason of confining the short arm 34 and its connecting-rod entirely within the body C and tube 20 and mounting the arm 34 on a cross-shaft 35, which has but a slight rotative movement when said parts are operated, I avoid and overcome all leakage. The connecting-rod 36 could be made to project through the top of the body C and be operated from the outside by a handle, lever, or otherwise; but this construction is not deemed as practical as that herein shown owing to the fact that when heavy and thick liquids are pumped leakage is sure to occur, the liquid forcing itself to the outside by the reciprocation of the rod. Then the liquid gums and hardens, and after a time, especially in winter, it is lnearly impossible to operate the pump. Where all the reciprocating parts are placed entirely within the body, lmore free action is obtained and leakage, with its objectionable features, is entirely eliminated.

The Valves, spout, pump-casing, and pump mechanism are all tinned to prevent corrosion.

' That I claim is- 1. ln a combinedpu-mp and measure, a tube, pump mechanism at the lower end of said tube, a spout and body at the top of said tube, a valve at the lower and outer end of said spout, a connecting-rod and arm Within said tube and body, a le'ver on the outside to operate said rod and arm, an adjustable beveled arm on the lever and lugs on the body to limit 'the movement of said lever, a rotating dial and indicator on said body to record the amount of liquid pumped, and means-on said lever to operate said dial atY the end of each stroke, substantially as described.

2. In a pump and measure, a tube having a spout-body at the top and a pump-casing at the bottom thereof, a valve in said spout and pump mechanism in said casing, a connecting-rod swiveled to said mechanism, and pivvoted toVv an arm 34 within the spout-body, a

lever 39 to operate said arm, a beveled adjustable arm on said lever and lugs on' said' body to limit the movement of said lever, and a dial on said body operated by means of said lever to record the amount of liquid pumped, substantially as described.

Witness my hand to the foregoing specification this 12th day of April, 1898.
